While some celebrities are trying to boost voter turnout by showing off $700 “Vote” boots, or posting thirst traps and ballot selfies, Noah Centineo, the 24-year-old star of “To All the Boys I’ve Loved Before,” is taking a different approach.

In a last-ditch effort to get Gen Z to the polls, Mr. Centineo and his friend Josh Heller, 33, created a voting-focused pop-up gallery in Los Angeles and have been inviting big-name influencers to tour the space. The idea is that social media posts from the pop-up — which features galvanizing neon slogans like “use your voice” — might encourage their followers to cast their ballots. The gallery isn’t just a photo opportunity; it’s also a way to educate and inspire influencers to vote and speak out on big issues.

“Until everyone in America votes, or a critical mass majority votes, we aren’t going to have a good understanding of who we are and of our total values and desires,” Mr. Centineo said.

influencer hot spot BOA Steakhouse on Sunset Boulevard, has become a place to see and be seen. Visitors like Kylie Jenner, the TikTok star Larray and Anastasia Karanikolaou (a.k.a. Stassiebaby) have posted content from the pop-up on social media. Mr. Centineo is leading by-appointment tours (occasionally barefoot but always masked) through Thursday, Oct. 29. People without millions of followers can tour the space virtually.
